HP Z820 Boot Warning: "932 Warning one of the QPI links not operating"

I have a HP Z820 E5-2670 1TB 16GB, NVIDIA QUADRO 4000 2GB, Intel Pro1000 PT Dual Port
that is giving me a post error "932 Warning one of the QPI links not operating". If I ignore the error the machine boots up without a problem.

Hrm, well i have never seen this particular error before but what i can tell you is the QPI link is what links the CPU to the chipset and/or another CPU in the case of multi-socket systems. Have you overclocked your GPU by chance?

It certainly links the two CPUs together as above and with those particular workstations there are meant to be 2 QPI links between the CPUs. You may not even notice performance degradation with just 1 QPI link working

If it's not under warranty or maintenance I would first reseat each CPU but it's more likely to be the motherboard. It's almost guaranteed that it is under warranty since the E5-2670 was only released Q1/12 and those workstations should have 3 years warranty, rightly so since it's more powerful than many servers.
